Seems like everyone had the same great idea at the same time: with comic-cons proliferating, and nerdlebrities making a circuit out of it, wouldn’t this be fine fodder for a realityish TV show/webisode of some kind? And wouldn’t actors who had starred in TV shows that had insanely fanatic fanbases but who didn’t get much airtime outside of that be the perfect people to do it?
It seems both Firefly’s Alan Tudyk and Nathan Fillion and Supernatural’s Rob Benedict and Richard Speight, Jr had the same idea. And both have turned to Indiegogo to bring these ideas to fruition.
